These SHS spring guides are the same as the full stainless ones sold by SHS, HC, Core, etc but the outer tube and cap are made from aluminum instead of stainless. The base and threaded core section are still stainless. These are for version 2 (M4, M16, MP5, and variants, G3, and M249) gearboxes. The main purpose of this upgrade part is to release torsion buildup in the spring that can cause premature failure and poor performance. This also increases the consistency of the velocity which improves accuracy. Because of the thickness of the ball bearing it also acts as a spacer which increases velocity.
Note: Like other spring guides of this design (and probably the same OEM) the mounting pegs need a little modification to fit in G&P gearboxes.
Specifications:
- Spacing thickness (the distance the guide spaces the piston forward measured from the back of the guide): 6.50 mm (.253 in)
- Stainless steel and aluminum construction
- 8 ball ball bearing
- Improves spring life
- Adds velocity
- Increases velocity consistency
